It's still really early in the Yukon Quest. My guess is that there's not a lot of racing going on right now but that there's a lot of positioning so that they'll be set up to make a move later in the race. There's always the possibility of someone making a surprise move, like Lance Mackey's famous, heroic run from Nulato to Unalakleet in the 2010 Iditarod, but it's the nature of surprises to be surprising (you can quote me on that). Competitive teams want to make sure that other contenders can be reeled in when the time comes to make a move, so you sometimes see them traveling together and keeping an eye on one another. That appears to be what's going on at the moment. Here's what it looks like on the race flow plot:
We're seeing six people traveling in three pairs, plus Sonny Lindner running alone. At the time this screenshot was grabbed Hugh and Brent had been traveling together for 3.5 hours. Abbie and Allen left at about the same time. Allen had a brief, er, "diversion" leaving Circle, but he caught up and they're now traveling together. The final pair is Kristy Berington and Lance Mackey. With each of these duos there are occasional passes, but the overall slopes of the line (i.e. speed) is remaining more-or-mess constant while they run down the Yukon towards Eagle. What we're seeing is strategy, not flat-out racing.
